Delay Relay

Time delay relays are simply control relays with a time delay built in. 

Their purpose is to control an event based on time.

The difference between relays and time delay relays is when the output contacts open and close: 

on a control relay, it happens when voltage is applied and removed from the coil; on time delay relays, 

the contacts will open or close before or after a pre-selected, timed interval.

Typically, time delay relays are initiated or triggered by one of two methods: 

Application of input voltage (On Delay, Interval On, Flasher, Repeat Cycle, Delayed Interval and Interval / Flasher).
Opening or closing of a trigger signal (Off Delay, Single Shot and Watchdog).
